http://whitehorserecords.co.uk/artists/rubix/attachment/rubix-profile-photo600x600/ Once merely an element to build shelter, materials have now become instrumental in the design of innovative building skins. Many newly developed materials are capable of adapting to external conditions physically, allowing the building surface to respond to changes automatically without the need for external energy input. Thermobimetals (TBM), one of those smart materials used in this installation, is a lamination of two metals together with different thermal expansion coefficients that can simply deform when heated and return to its original shape when cooled. The interactive installation utilizes this intelligent movement, responding to a strategically-positioned heater by bulging and crimping at the mid-section. When cooled the piece returns to its svelte shape.
